Introductory Optimization - Pedal

Training:

You can find all relevant data for this tutorial in the Example folder!

Step 1: Create a new project

In a first step, you need to create a new project. All data (geometry and configuration) directly will be copied and saved in a new project-folder, located in your workspace:

• Start AMendate
• Create a new project

• Enter a projectname and save the project
• Open the newly created project

Step 2: Model generation

• Upload all relevant stl files by clicking on the symbol in the objects/surfaces area
• select all stl files

• The uploaded objects are listed in the objects/surfaces area.

• Assign a Material to each object/surface and enter the specific values for the Young's Modulus and poisson ratio in the Material Editor.

• Activate the option design space for the relevant stl file. Only one volume can be selected as such

Step 3: Definition of boundary conditions

Go to the boundary conditions tab to enter the loads and fixations as follows

• Objects "interface1L" and "interface1R" each experience a force of 18904 N in x-direction (conditions 1L, conditions1R).
• Objects "interface1L" and "interface1R" each experience a force of 17792 N in y-direction (conditions 2L, conditions2R).
• Objects "interface1L" and "interface1R" each experience a force of 15701 N in x-direction and 14137 N in y-direction (conditions 3L, conditions3R).
• Objects "interface1L" and "interface1R" each experience a force of 19483 N in x-direction (conditions 4L, conditions4R).

• Objects "interface2", "interface3", "interface4" and "interface5" are all fixed in x-, y- and z-direction (=0) (dis1, dis2, dis3, dis4).
• A total of 8 forces and 4 fixations should have been created as a result.

All boundary conditions are assigned to the load cases. The number of load cases can be changed using the "+" or "-" characters. The assignment of the boundaries to the load cases can be made in the boundary conditions or load cases area.

• Active in load case 1: dis1, dis2, dis3, dis4, conditions4L and conditions4R

• Active in load case 2: dis1, dis2, dis3, dis4, conditions1L and conditions1R

• Active in load case 3: dis1, dis2, dis3, dis4, conditions2L and conditions2R

• Active in load case 4: dis1, dis2, dis3, dis4, conditions3L and conditions3R

Step 4: Definition of optimization parameters

Switch to the optimization area. You can find more information about the parameter selection here.

• Choose the design type normal.
• Enter the optimization goal stress: 600 MPa

All Inputs can be viewed and checked in the configuration file. The file should look like this.

Step 5: Save the project

Step 6: Starting the optimization and visualizing the results

If all data are correct, the optimzation can be started and tracked in the results area.

All result iterations are displayed as soon as they are available. The progress of the optimization can also be monitored via the AMendate log file. Furtheremore you are able to stop the optimization in this selection area. A restart however is not possible without further expert settings.

The optimization is finished after 64 iterations (optimizationtype: optimizing).
